Even though WiFi coverage is growing every day, it can still be incredibly difficult to get a reliable connection when you need it. Karma Go puts the power of a hotspot in your hands, thus ending the hunt to find the next WiFi signal. At 2.9 inches it's small enough to slip into your pocket, and with a 5 hour battery life and no wires to connect, it's portable and easy to operate. It's just as hassle free on your wallet as well, with no contract, monthly fees, or expiring data — all while supporting as many as 8 wireless devices at a time on nationwide 4G LTE.

Bring the technology of your bike up to the same standards as your car with the Cobi Connected Biking System. Designed to leverage the smartphone you're already carrying around, it pairs a physical dock that installs on your handlebars, with a custom app that's built with cyclists in mind. The dock itself features a built-in light and the ability to charge your device, and there's also optional automatic brake lights and turn signals. Finally, there's a thumb controller, which works with the app to let you control your music and access features like speed, time, distance, climb rate, and elevation data, navigation, fitness tracking, and more, all without moving your hand.

When it comes to creating a great virtual reality experience, there are few things more important than what your eyes see. So it only makes sense that a company with a history of great optics would make a great solution. The Zeiss VR One Headset blends wide-ranging device support with the company's precision lenses to create an immersive experience. Thanks to a slide-out tray, it can support most smartphones with display sizes between 4.7 and 5.2 inches, and offers a see-through front shield for augmented reality apps, ports to allow access to the device's headphone and charging jacks, ventilation openings for increased airflow, and, for the bespectacled among us, support for wearing your eyeglasses while you're using it.

It may sport airplane-like looks, but don't be deceived — the Carbon Flyer Video Drone is in many ways just as capable as its quad-propellered brethren. The airframe is built from carbon fiber, and assembled with carbon nanotube-enhanced epoxy for bonds that are stronger than steel welds. Features include dual high-power motors, an onboard camera for video recording, a protective nose cone and side casings, and hot-swappable, rechargeable lithium ion batteries. And thanks to Bluetooth 4.0, you get a 240-foot operating range, as well as an intelligent app that allows for one-handed control.

We all know that Wi-Fi passwords can be a royal pain. While necessary to keep unwanted devices from snooping around your network or siphoning off precious bandwidth, they also create a barrier for guests. The Keewifi Router solves these problems by choosing to not use passwords at all. Instead, it uses proximity technology to make secure connections to devices. You simply hold your device close the syncing panel and it securely authenticates in seconds, and thanks to 802.11ac support, you're not sacrificing performance for convenience.

We spend about a third of our time sleeping, so the mattress you sleep on every night is incredibly important. But when you lie on a bed for five minutes in a mattress showroom, it's impossible to judge how you'll sleep through the night - and the commissioned salesperson hovering doesn't help. Casper was designed with the bedroom in mind, not the showroom, and features premium latex foam for cooling and memory foam for comfort and support. In fact, you can avoid the showroom altogether as Casper comes compress-shipped right to your door. Make sleep a priority again with this impeccably designed, outrageously comfortable, and hand-crafted mattress made in the U.S.A.

Having a few drinks with friends is nearly always a good time. Trying to get home if you've overindulged, not so much. The Breeze Breathalyzer is here to help. Using an advanced electro-chemical fuel cell sensor, this pocketable gadget delivers law enforcement-grade results to a companion app via Bluetooth LE, letting you know your current BAC and how long it will take you to get sober — or as the app calls it, Back to Zero — and helpfully offering built-in connections to cabs, Uber, local restaurants, and even nearby hotels, so you'll have no shortage of options if you need to get home or kill a little time before hopping back behind the wheel.

You don't need to be a superhero/mutant/sorcerer to shoot fire from your hands. All you need is the Pyro Handheld Fireshooter. This very real, very crazy gadget was designed for illusionists, magicians, and other performers, sits on the underside of your wrists so it can be hidden by a sleeve, is activated by a remote switch you hide away in your opposite hand, and can be fired up to four times without reloading. Needless to say, you're going to want to read the entire instruction manual before you start throwing flames at everything you see.

Most fitness trackers are designed only to record your activity, measuring your movement throughout the day and maybe even supplying some performance metrics. The Moov can certainly do all that, but it serves as a personal trainer, too. By pairing either one or two of the waterproof 9-axis motion sensors — the number depends on the activity you're doing — with your phone over Bluetooth 4.0, the companion app is able to give you audio and visual instructions while you're working out, serving as a virtual personal trainer, and helping you to maximize your efforts while avoiding injury.

Dremel's known for making tools that are great for modifying 3D objects, not for creating them from scratch. Still, the company's bringing the same reliability from their hand tools to the Dremel Idea Builder 3D Printer. Designed to be an easy first step into 3D printing, it features easy-to-use software, a pre-installed extruder for fast initial setup, and a full-color touch screen for object previews. As for specifics, it offers a 100 micron resolution, ten available colors of plant-based filament, and a large, removable build platform that lets you create objects up to 9" x 5.9" x 5.5" in size.

Most modern home security solutions have a couple things in common: Internet connectivity, which is great, and cameras, which are not so great — if you're extra worried about privacy. The Point Home Security Device gives you the benefits of the former without the concerns of the latter. Point requires no wires, as it connects via Wi-Fi, runs on regular replaceable batteries, and features built-in lights and a speaker to communicate at home and an app for when you're away. An array of sensors includes a particle detector to detect smoke and other common home hazards, a thermostat, a humidity sensor to check for water leaks and/or mold, and a microphone to sense things like doors opening or windows breaking. And since all the analysis is done on the device, no audio is ever recorded, or even sent out over the 'net. Just the way we like it.

Instant communication with a group can be a clunky, arduous process. So when you need to communicate right now, the Onyx Communicator might be the best choice.

Whether it's a team hard at work organizing an event, coordinating a surprise birthday party, or an emergency, the Onyx Communicator puts group communication at your fingertips.

Even when you're off the grid, having a power supply for your camera, phone, or tablet is imperative. The Switch 10 USB Multi-Tool from Goal Zero just became an essential element for your pack, with a 7-watt solar panel, and a replaceable, lightweight, lithium battery that powers up from any USB. Charge your phone, camera, tablet or any USB-powered device, or switch over to the flashlight for light in a dark spot. It even comes with a small fan, making it a true all-in-one power solution.

There are plenty of connected camera options out there. But there's only one that's totally wire-free. The Arlo Smart Security Camera is a 100% wireless security camera solution, offering 720p video resolution and the ability to run up to 6 months on a single set of batteries. The cameras are waterproof, so they're outdoor-friendly, with motion sensors for real-time alerts, night vision capability for clear images even in the dark, and magnetic mounts that make it easy to move them from place to place. The starter kit includes two cameras, four mounts, and a smart base station that can also talk to other devices; extra cameras sell for $170 a pop.

The relationship between sound and vibration is common as you walk through life. But capturing that during a multimedia experience has proven to be quite difficult. Woojer is a wearable audio accessory that provides low frequency vibrations and a physical bass sensation — similar to a concert experience or cinema surround sound. It's not the first to market, but is the first that doesn't require a backpack or some sort of special headset. It's a plug and play immersive experience ideal for music lovers and gamers that is the size of a matchbox.

It's a speaker. It's a music system. And much more. The Amazon Echo is a new cloud-connected gadget designed around your voice. Always on, you wake it by saying "Alexa", then asking it questions or giving it commands. Want to know the weather? Just ask. Want to add something to your shopping list? Done. In the mood for some Beatles? Say the words. With dual down-firing speakers, it produces surprisingly rich sound, and thanks to integrated Bluetooth, it also syncs with the Echo app, and lets you stream music from any source you want — although you probably won't have to use the feature very often, as it offers built-in support for your Amazon Music Library, Prime Music, TuneIn, and iHeartRadio.

To keep your house safe, you could go the traditional route and have an elaborate security system installed. Or could just grab a Cocoon Home Security Device. This single, simple device aims to protect your entire home by using Subsound technology to sense activity even in other rooms. It learns your normal activity schedules to reduce false alarms, and also adds in a pet-friendly motion detector, a loud siren designed to disorientate intruders, and a wide-angle, night vision-capable HD camera with high-quality microphone to let you check in on things remotely and record evidence if necessary. All with only one wire to plug in: the power cord.

With cameras seemingly crammed into every device we use, we've never taken so many photos. Which means we've never had to deal with displaying so many photos. The Fireside Smart Picture Frame aims to make it easy. A combination service, app, and digital picture frame, Fireside will bring all your photos together in a secure cloud storage solution, make them searchable, and most importantly use an intelligent algorithm to put them in context, letting the frame automatically show photos that are relevant to that day. For example, wedding and honeymoon photos on your anniversary, photos from previous birthdays on your birthday, and even shots that correspond to the weather outside. It's like having a personal photo concierge right on your shelf.

There's little doubt that drones can take some amazing footage, but if you're busy at the controls, odds are it's not getting footage of your most important subject: You. The Hexo+ Drone solves this problem by automatically following you using the framing parameters you set up using the app. It can move at speeds of up to 45 mph, so it can track you even if you're in a vehicle or on a bike, its mount is GoPro compatible, it features six propellers and fail-safe software so it can land easy even if there's a problem, and its lightweight foldable frame makes it easy to pack around. It's like having your own personal film crew, without the extra costs and pushy directors.

News about 3D printing seems to be everywhere these days, but the barrier of entry for most consumers makes it seem out of reach.

It produces high resolution prints on demand with no software to download, works over WiFi, and even has a battery powered option for on-the-go printing.
